Answer:
- 3
Step-by-step explanation:
Using the law of logarithms
x = n ⇔ x = ![b^{n}](https://tex.z-dn.net/?f=b%5E%7Bn%7D)
let
(
) = n
(
) = n, then
= ![b^{n}](https://tex.z-dn.net/?f=b%5E%7Bn%7D)
Since bases are the same on both sides then equate the exponents
⇒ n = - 3 → (4)
Answer:
Step-by-step explanation:
hello :
5(x + 7)² = 245
(x + 7)² = 49
x=0 is solution but you have other solution -14 because :(-14+7)² = (-7)² =49
here is an solution Step-by-step :
(x + 7)² = 49 means : (x + 7)² = 7²
(x + 7)² - 7²=0 use identity : a²-b² = (a-b)(a+b)
a=x+7 and b= 7
(x+7-7)(x+7+7) = 0
x(x+14)=0
x=0 or x+14=0
so : x=0 or x= -14
The difference in the dogs weight from 2 years ago is -0.83
Just add 41,300,000 to 50,500,000. That is 91,300,000.00 tons. Scientific Notation just moves the decimal point to the beginning. So it would be 9.13*10^7
Answer:
I believe the answer is 10/x.
Step-by-step explanation:
A quotient is a result obtained by dividing one quantity by another and sence we don't know what x is it will have to just be an algebraic equation like the question says.
